Y'know. It dawns on me that if the thunder spirit was a mommy MILF hag love UOOOOOOOH TAKESHIIII character. This entire speech he's giving at the end would be potentially very spicy...

Then again I guess if you want to take a BL view of it, it would also be potentially spicy. I mean what is he planning to do? Share his power by linking together and going inside of him? I mean he is a spirit after all, how are they going to connect and how is he going to empower him?
